Engadget noticed that two startups are putting together software that will allow apartment-dwellers to pool their DSL connections in order to improve overall bandwidth. Now you can keep those torrents going while you frag fools with split-second precision from across the map. It could work, so long as everyone else you're sharing with doesn't increase his or her bandwidth consumption as well. It'd speed up those painful Xbox 360 downloads, too.
Alternately, set up a Splitronic Broadband Aggregator to snag two WiFi connections out of the air and automatically balance your broadband usage across the connections.
